Technical Notes
The DS821 servo is a powerful, accurate sport
digital servo recommended for RC airplane applications up to
1.20-size. For helicopters, the DS821 operates best with
30-size glow models, and up to 50-size electric. Loads and
vibration in larger models may cause premature failure of
the servo resulting in damage or injury to property and
persons.
Important: Do not use liquid thread
lock with the DS821-R servo!
Do not use any form of liquid thread lock to
secure the servo arm screw to the output shaft of the DS821
servo. Chemicals in these liquids react with the
polycarbonate gear set causing the plastic to become
brittle, fracturing the final output gear.
